SPECIFICATION forming part of Letters Patent No. 595,079, dated December 7, 1897'.

Application filed July 29, 1897. Serial No. 646,292. (No model.)

To (LZZ whom, it nm concern.-

Be it known that I, XVILB UR STEPHEN Sonn- DER, a citizen of the United States, residing at Brooklyn, Kings count-y, State of New York, have invented certain new and useful Improvements in Methods of and Means for Mak in g Matrix-Bars for Line-Casting Machines, of which the following is a full, clear, and exact specification.

This invention relates to the manufacture of matrix bars or plates designed for typecomposing and line-casting machines, particularly such matrix-bars as are employed in the monoline composing-machine, disclosed in Letters Patent No. 506,198, issued in the United States October 3, 1893, to V. S. Scudder, assignor to the Monoline Composing Company.

Matrix-bars of the character alluded to have been manufactured by electrodeposition of copper or other metal, as described in Capeharts Letters Patent No. 529,440, issued in the United States November 20, 1894; but according to the method or order of procedure set forth in this patent independent or separate dies require to be individually assembled relatively to the recessed edge of a matriXbar blank, which is attended by difficulties and results in a greater or less number of imperfect matrix-bars. The assembling of a number of dies ormetal types which have been separately cast multiply inaccuracies to a considerable extent, which it is very desirable to avoid.

The chief objects of my present invention are to improve and simplify the manufacture of matrix bars having intaglio characters formed in metal which is electrodeposited in recesses in the edges of the bars, to avoid inaccuracies in the completed matrix-bars, and to secure from type bars or slugs, each formed as an integral structure with relief characters, any desired number of matrix-bars which will bear accurate reproductionsin intaglio of the relief characters and will be positioned with exactness and therefore be perfect in every respect if the type bars or slugs are perfect, which is rendered possible by my invention.

The invention also has for its objects to avoid the presence of disconnected and independently-movable dies or types in connection with matrix-bar blanks during the production of the intaglio characters by electrodeposition of metal and to provide a new system wherein the cameo or male characters by which the intaglio characters are created in the matrix-blanks are practically an integral structure susceptible of being handled or manipulated in substantially the same manner as a single type character without possibility of one character becoming disarranged, moved, or shifted independent of another during the process of producing the electrodeposited intaglio characters.

These objects are accomplished in the manner and by the means hereinafter described and claimed, reference being made to the ac companying drawings, in which- Figure 1 is a side elevation of a primarymaster-inatrix blank forming a part of my invention. Fig. 2 is a similar view of a part of the type or die holder. Fig. 3 is a similar View showing the completed type or die holder properly connected with the pri1nary-mastermatrix blank preparatory to producing the intaglio characters in the edge of the blank by electrodeposition of metal. Fig. 4 is a similar view showing the completed primary master-matrix from or by which'the relief characters of the type bar or slug (best seen in Figs. 5, 6, 8, and O) are produced in a casting-machine. Fig. 5 is a similar view showing the type bar or slug properly connected with a matritebar blank designed to be provided with intaglio characters in'one edge and to be used in a type-setting and line casting machine, as the monoline. Fig. 6 is a similar View showing the appearance of the parts represented in Fig. 5 after the copper or other metal has been electrodeposited. Fig. 7 is a similar view of the completed matrix-bar. Fig. 8 is a detail side elevation of the type bar or slug from or by which any required number of matrix-blanks such as shown in-Fig. 7 may be produced, and Fig. 9 is an edge view of the type bar or slug.

In order to enable those skilled in the art to make and use my invention, I will now describe the same in detail, referring to the drawings, wherein- The numeral 1 indicates a primary-master'- matrix blank consisting of a rectangular plate of brass having in one edge a' series of recesses 2, constructed in any manner suitable 'to receive and anchor the copper or other metal deposit, as will hereinafter appear. This blank is also provided near one end, in the edge containing the recesses 2, with a notch 3 to engage with a type or die holder composed, preferably, of a lead plate 4, having its ends formed as thickened pillars or posts 9, between which one surface of the plateis constructed, by suitable milling-tools, with transverse grooves 5, designed to receive the dies or cameo-type bodies 6. The grooves 5 are exactly spaced in their distances apart and are of uniform depth. The dies or cameotype bodies bearing the characters which it is desired to reproduce are placed in the grooves 5 in the required order of sequence, and when the relief type-faces are properly alined,which is easily accomplished, the dies or cameo type are secured in a fixed position relatively to the plate by waxing, soldering,or otherwise. This type or die holder'is then connected to the primary-master-matrix blank, as shown in Fig. 3, a gage-lug 7 on the edge of the type or die holder entering the recess 3 in the edge of the blank 1, thereby placing the faces of the cameo type in proper relation to the recesses 2 in the blank with respect to the length of the blank and of the type or die holder. The edge of the type or die holder is also provided at or near each end with opposite gage-lugs 8, which embrace the edge of the master-matrix blank 1 and position the two parts sidewise, whereby it is possible to exactly register the faces of the cameo characters of the types or dies 6 with the centers of the recesses 2 of the blank 1. The blank 1 and the type or die holder are now connected together in any proper manneras, for instance, by tie-wires 10-and they are insulated by waxing or otherwise, except at the recesses 2 of the blank 1 and the cameo characters of the types or dies 6, the dotted lines, Fig. 3, indicating about the parts which are not insulated by waxing. The connected parts are then suspended in a proper bathas, for instance, by

a wire 21and the relief characters of the type or die holder are exactly reproduced in intaglio in the master-matrix blank 1 by electrodeposition of metal. By this means I produce the primary master-matrix 12. (Best seen in Fig. 4.) Accuracy is essential in producing the primary master-matrix, as from it the large number of circulating matrix-bars employed in the type-setting and line-casting machine are obtained, as will hereinafter appear, and any deviation or error in the manufacture of the primary master-matrix will appear in the circulating matrix-bars. The master-matrix bar 12 (shown in Fig. 4) presents in intaglio form the required characters, one in juxtaposition to another, equally spaced and exactly in a center line running longitudinally thereof. This master-matrix is then employed in any suitable casting-ma chine, such as a line-casting machine, to obtain the type bar or slug 13, having on one edge the cameo or male characters 14 and at each end transverse thickened pillars or posts 15, provided with three projecting gage-lugs 16, 17, and 18. This type bar or slug is connected with a matrix-bar blank 19, as represented in Fig. 5, which blank is positioned lengthwise by the gage-lugs 18 and sidewise by the gagelugs 16 and 17in such manner that it is possible to exactly position the faces of the cameo characters of the type bar or slug 13 relatively to the bottoms of the recesses in the matrixblank 19. These parts, connected together in this manner, are then insulated by waxing, substantially as described in Oapeharts patent referred to, and are suspended in a suitable bath, so that when the circuit is closed electrodeposition commences from both sides and the copper or other metal is gradually built up in the recesses and about the cameo faces of the relief characters on the type bar or slug 13. The dotted lines, Fig. 5, indicate about the parts which are not insulated by waxing. The parts as they are taken from the bath will appear substantially as represented in Fig. 6, the portion 20 being the excess of the copper deposit, which is removed by suitable milling-tools or otherwise, after which the parts are separated and the completed matrix-bar 22 (shown in Fig. 7) is the result.

The ends of the type bar or slug 13 are made in the form of thickened pillars or posts to secure a greater quantity of metal at these points as compared to the central body of the slug. I find that this construction counteracts the tendency of the metal to shrink which naturally follows the cooling of a cast solid line of type characters such as a type-high printing-bar. The thickened pillars or posts effectually hold the body of the slug between the posts and avoid irregular shrinkage. The slug, or, rather, the pillars or posts, are also cast with the projecting gage-lugs 16, 17, and 18, which serve, as before stated, to position the matrix-blank 19 lengthwise and sidewise relatively to the type bar or slug, so that in the completed matrix-bar 22 the required characters are in juxtaposition to one another, are equally spaced, and are exactly on a center line running longitudinally of the bar. The matrix-blanks 19 are carefully prepared from suitable metal, preferably brass, which is found to be the best working material, al-

though other metal may be employed. These blanks do not require further explanation, however, as they are set forth in Capeharts patent referred to. In connecting the matriX-blank 19 with the type bar or slug 13 the two parts are squeezed together until the matrix-blank comes squarely to rest against the type bar or slug, it being understood that the cameo type on the bar or slug 13 have been cast the proper height, or the height it is desired the intaglio characters should have in depth in the completed matrix-bar, Fig. 7.

A very important part of my invention resides in the fact that the several cameo or relief characters by which the intaglio characters in the matrix-bars are reproduced are practically an integral structure susceptible of being handled or manipulated substantially in the same manner as a single piece or a single type character without the possibility of one character becoming disarranged, moved, or shifted independent of another during the manufacture of the electrodeposit intaglio characters.

Anotherimportant part of the improvement resides in the construction of the type bar or slug 13 with the positioning gage-lugs 16, 1'7, and 18, by which the matrix-blank 19 is positioned lengthwise and sidewise, and another feature of importance is the thickened pillars or posts by which irregular shrinkage of this cast type bar or slug is effectually prevented. I am able by this means to reproduce by this type bar or slug any required number of matrix-bars, each of which will be provided with accurate and perfect intaglio characters exactly spaced and positioned on the edge thereof relatively to its center line, thereby obtaining by simplified means type-high printing-bars presenting such accuracy in the location and formation of the intaglio characters that the high perfection desired in the printing art where line-casting machines are employed is rendered possible, while all the difficulties attending prior methods for this purpose, particularly those methods which involve the assemblage of independent dies or cameo type in producing each matrix-bar, are avoided.

My invention is more particularly useful and advantageous in the manufacture of matrix-bars each having a group or plurality of intaglio characters in one edge, such as are circulated in the monoline composing-machine hereinbefore referred to; but it is also useful in the production of matrices for other line-casting machines.

Having thus described my invention, what I claim is- 1. The method herein described of making a matrix-bar, which consists in constructing a primary master-matrix, reproducing the character-face thereof in relief on the edge of a plate, adj usting the relief character-face to the recessed edge of a matrix-blank, insulating these parts except where an electrodeposit is to be made, and electrodepositing a metal to produce in intaglio in the recessed edge of the blank the relief character-face of said plate, substantially as set forth.

2. The method herein described of making a matrix-bar, which consists in fixing relief characters in a plate, adjusting this plate with its relief characters relatively to recesses in the edge of a primary-master-matrix blank, insulating the parts except where an electrodeposit is to be made, electrode1; osit-ing a metal to produce in intaglio in the recessed edge of the master-matrix blank the relief characters of the plate to obtain a primary master-matrix, casting from this master-ma trix a type line or slug having relief characters, fitting the relief characters of the type line or slug relatively to recesses in the edge of a matrix-blank, insulating these parts except where an electrodeposit is to be made, and electrodepositing a metal to produce in intaglio in the recessed edge of the matrix blank the relief characters of the type line or slug, to obtain a completed matrix-bar bearing in one edge a plurality of intaglios, substantially as set forth.

3. A type bar or slug having a solid line of relief characters on one edge and provided with gage-lugs to position the type bar or slug, lengthwise and sidewise, with relation to the recessed edge of a matrix-blank, substantially as set forth.

4. The method herein described of making a matrix-bar, which consists in obtaining a primary master-matrix by electrodeposition of metal from relief characters of types or dies, casting a type bar or slug from the primary master-matrix, fitting this type bar or slug to the edge of a recessed matrix-blank, and obtaining a completed matrix-bar by electrodeposition of metal in the recesses of the matrix-blank about the relief characters of the type bar or slug, substantially as set forth.

5. The method herein described of making a matrix-bar, which consists in preparing a primary master-matrix by fixing relief characters in a plate having gage-lugs, fitting a recessed blank lengthwise and sidewise relatively to the plate through the medium of said gage-1n gs, electrodepositin g metal in the recesses of the blank about the relief characters to reproduce the latter in intaglio and obtain the primary master-matrix, casting from said master-matrix a type bar or slug bearing a solid line of relief characters, positioning this type bar or slug lengthwise and sidewise relatively to the recessed edge of a matrix-blank, insulating the parts, except where an electrodeposit is to be made, and electrodepositing a metal to produce in intaglio in the recessed edge of the matrixblank the relief characters of the type bar or slug, to obtain a completed matrix-bar bear- IIO to opposing gage-lugs on one edge, and cameo type fixed in said grooves With their cameo characters located centrally between said opposing gage-lugs, substantially as and for the purposes set forth.

In testimony whereof I have hereunto set I 5 my hand this 15th day of July, 1807.
